回答1:

You will need to create two triggers for the job.

The first trigger for the 2nd Monday:

0 0 12 ? 1/1 MON#2 *

And the second trigger for the 4th Friday:

0 0 12 ? 1/1 FRI#4 *

According to the docs, you can specify (e.g.) the 2nd Monday of the month by putting MON#2 or 1#2 in the day-of-week field.

The '#' character is allowed for the day-of-week field. This character is used to specify "the nth" XXX day of the month.

But composing these like MON#2,FRI#4 in a single cron expression is specifically prohibited, so you need multiple CronTriggers.
